UNITED STATES WILLIAM H. POWERS, OF EUGENE, OREGON.

SHOE-SHINING MACHINE.

Application filed June 23,

To all whom it may concern:

Be it known that I, WILLIAM H, POWERS,

"a. citizen of the United States, residing at quired for the practice of the shoe shining trade.

I attain these objects with the mechanism illustrated in the accompanying drawing, in which- Figure I is a perspective view of the entire box with shaft and brush attached ready for operation.

Fig. II is a vertical, longitudinal section through the box, exhibiting the motor Within the box.

Fig. III is a section through Fig. II along the line AA, also illustrating constructive details of the flexible shaft.

Fig. IV is a perspective view of the end of the flexible shaft.

Similar numerals refer to similar parts throughout the'several views.

The electric motor 1 is placed in a box 2 having a hinged lid 3 and a handle 4 on the lid for convenient transportation. The terminals 5v for the motor are located outside the box, and so is the rheostat 6. For convenience of illustration the connecting wiresbetween terminals, rheostat and motor are shown exposed, in actual practice these wires should be rotected from damage by being embedded in the walls of the box.

Attached to the motor shaft by means of suitable couplings 7, is the flexible tube 8, and within the tube the flexible shaft 9, the latter essentially composed of a chain which is rotatably confined within the tube. Attached to the other end of the chain is a solid axle 10 having a collar 11 which rests against the end of the flexible tube. The

rotary brush 12 is slipped on the axle and compelled by the key 13 to rotate with the shaft. The handle 14 permits a convenient manipulation of the brush. A small plate 15, plvoted eccentrically tov the end of the axle, will during rotation be thrown over the core of the brush, and prevent the latter from flying off the axle. When the motor is stopped by the manipulation of the rheostat the plate 15 can readily be switched from the core on to the end of the axle, and the brush can be quickly removed and replaced by another brush.

When readyto be moved to some other location, the box is disconnected from the electric circuit, the couplings on the motor shaft are uncoupled, the shaft is coiled up and placed with the brushes and other paraphernalia into the box, and everything is ready for moving.

Having thus described my invention, it will be seen that my objects have been accomplished and, although I have shown the preferred form of construction, I reserve to myself the right to make minor changes, providing I do not violate the spirit and principle of my invention; especially may the electric motor be replaced by a water motor, in which case, of course, the rheostat and terminals may be omitted. The rest of the structure requires no material change.

I claim:

1. In a shoe shining machine, the combination of the flexible shaft, and a rotary brush, with a solid shaft attached to the end of the flexible shaft and entering the hub of the rotary brush, an end plate pivoted eccentrically to the end of the solid shaft, said end plate being swung by centrifugal force over the hub of the rotary brush to hold the rotary brush on the solid shaft. I

2. In a shoe shining machine, a solid shaft having one end adapted to be attached to a flexible shaft, an end plate pivoted eccentrically to the other end of said solid shaft, the greatest length of said end plate not to exceed the diameter of the solid shaft, a collar intermediate the two ends, and a key longitudinally with the solid shaft from the collar to the end plate.

Signed by me at Eugene, Oregon, this 16th day of June 1920.

WILLIAM H. POWERS.
